The X-class was a class of two Birney trams imported from United States manufacturers JG Brill Company and St Louis Car Company by the Melbourne & Metropolitan Tramways Board.
In June 1924 both entered service from Hawthorn depot on the Power Street to Hawthorn Bridge service.
In 1928 both were transferred to Glenhuntly depot to operate the Point Ormond route.
They also operated night services taking them as far as Brighton East, Malvern East and Coburg North.
